Magpul PMAG 10 AC AICS Short Action Magazine – 7.62×51 NATO/.308 Win, 10-Round, Black (MAG579)

The Magpul PMAG 10 AC (MAG579) is a purpose-built 10-round magazine engineered for precision rifle platforms running short action AICS (Accuracy International Chassis Systems) pattern bottom metal. Designed for cartridges built on a 0.470″ case head, this magazine offers broad compatibility with popular chamberings including 7.62×51 NATO, .308 Winchester, 6.5mm Creedmoor, .260 Remington, 7mm-08 Remington, and .243 Winchester, among others — accepting cartridge overall lengths of up to 2.86″.

Built to Magpul’s next-generation polymer standards, the MAG579 features impact and crush-resistant construction that holds up under demanding field and match conditions. A self-lubricating follower ensures consistent, reliable feeding round after round, while a long-life stainless steel spring maintains constant tension for dependable performance over the magazine’s lifespan. Paint pen dot matrix panels on the bottom of the body allow for easy identification marking — an invaluable feature for competitors and serious precision shooters managing multiple magazines. The flared floorplate improves handling during reloads and is designed for straightforward disassembly and maintenance.

**Compatibility Note:** Not compatible with smaller base diameter cartridges such as .223 Remington, .220 Swift, or .300 AAC Blackout, or with larger short action magnum cartridges. Due to the wide variety of aftermarket receivers, stocks, chassis, and bottom metal, minor fitting may be required. Not compatible with Accuracy International AE rifles.

Whether you’re building out a long-range precision chassis rifle or upgrading your existing AICS-pattern setup, the Magpul PMAG 10 AC delivers the reliability, durability, and consistency that serious shooters demand.
